I am the original owner of 1983 h34 with a yanmar 3gmf freshwater cooled engine. I have done all regular routine maintenance suggested by the owners manual oil, trans, belts, impeller and so on. Replaced normal ware and tear items of the years. Winterized engine every year with no issues, engine startup every time on the first time. Knock wood! I have no engine hours meter so I can only approximate the hours to be 3500 - 4000 hrs.
Question is when do my fellow boaters replace or do a complete overhaul.
I ask this because I have a bobcat excavator with roughly the same size engine and I consider this engine to be used extremely hard compared to the boat.
The bobcat service center doesn’t recommend any major service or overall until 15,000-20,000 hrs as long as routine maintenance is done.
Should I be saving up for big bucks, am I way overdue, or put it out of my mind for now. I have gotten mixed views on this.
Some people say it’s a time bomb, others say that it’s just broken in.
Now I don’t want to sound like I am tooting my horn but when is say the engine looks and runs just like new it does. I am a firm believer in preventive maintenance.
